Speaking of being a maverick on the red carpet, Gemma reveals that there's one star who's inspiring her style. 'I know it's been talked about a lot but I think Kristen Stewart is dressing so well at the moment. I love her attitude when she's on the red carpet. She's like [scowls] "this is it". She's the best at the moment in my opinion.'

Was there a scene in the book that you were particularly looking forward to shoot in ‘The Twilight Saga: Breaking Dawn – Part 2′?

I’ve enjoyed a lot of different beats in the ‘Twilight’ story, but I was really looking forward to doing the arm wrestling scene with Kristen. It’s one of the big moments for Emmett, and the fans are really looking forward to it. It was fun to shoot. When I first read it in that book I was excited because Emmett finally had a one-on-one scene with Bella, and not just human Bella, but vampire Bella. We had a great time shooting it. I wish we could’ve spent a full day doing it just because I had so much fun doing that scene, but I loved every second. It’s a funny scene.

Kristen Stewart becomes a very different Bella in this film. How was it for you witnessing that transformation while shooting?

The transformation Kristen did with becoming “super” Bella was really interesting. I mean, she’s a whole ‘nother character, she made up a whole ‘nother character. And I spoke to Stephenie Meyer’s about it and she was just so impressed by it. Going through the sense of being a newborn vampire, all of the heightened senses, being able to smell really well, see really well, fight really well – she done such an amazing job showing that. And I couldn’t really tell, I think my make-up is the most pale out of anyone’s, I don’t know what it is – it’s super pale (laughs), but Kristen looked still just as beautiful.

The Australian hunk appeared alongside the actress in Snow White and the Huntsman. Chris feels relieved that despite appearing in hit movies such as Thor and Avengers Assemble, he can still maintain some normality in his life. The star has sympathy for Kristen, who hits headlines all over the world for both her career and private life.

“I think it’s a different sort of fame. With the utmost respect, Twilight’s certainly a teen audience… Sort of hysterical kind of fanbase, you know? Whereas Avengers is across all ages and people just love the films – and it’s a little different from what she experiences,” he told the latest edition of British magazine Empire. “I am, in my everyday life, most of the time, not looking like Thor. Whereas the character she played in Twilight and her walking down the street, they’re pretty similar – they’re both human and relatable.

“I think for that reason, it’s when the character is even more relatable and closer to who you are in your everyday life, the line gets blurred. The Avengers was a different thing and we certainly didn’t have hundreds of people outside our hotels like they do.”Source | via

To prep for the final film, in which Kristen Stewart's character, Bella, transforms into a vampire, stunt coordinator Jeff Imada tells Us the actress "did drills, like martial-arts stick training. We'd do three hours of choreography on Saturdays, Kristen's day off. She's a pretty physical girl!" Even when Stewart broke her thumb, "she toughed it out," adds Imada. "She said, 'Keep going!'"

Were you happy with how Cosmopolis was received?
No, I would've liked it to have made half a billion dollars at the box office! [laughs] The movie was received like an art film, which is to say it did OK in the big cities. Naturally you always want the biggest audience you can get, just as long as it doesn't cause you to compromise your moviemaking.

Why did you cast Robert Pattinson as limo-riding antihero Eric Packer?
Eric is in absolutely every scene, so you need an actor who is interesting and charismatic enough to look at for the entire movie. You want someone who can really come up with surprises and angles, and has a level of stardom that will support the movie. He also had to do a credible New York accent. All of that led me to Rob.

Stewart of course is on everyone’s mind right now as the last chapter of the Twilight Saga rakes in cash at the multiplex, but it’s easy to forget that she’s also carved out a nice niche for herself and done some of her best work in smaller scale films like Into the Wild, The Runaways, Welcome to the Rileys and now On the Road.

In front of cameras and in front of the media since before she was even a teenager, a lot of ink has been spilled about Stewart and her personal life so it’s not all that surprising she’s kind of a guarded presence. She has a reputation for being a difficult interview, but I don’t blame her. This is what happens in a world where a young woman’s behavior can be trumpeted as a “scandal” in tabloid headlines even when whatever it is all falls well within the boundaries of the law. We’re a society that seems to need to build people up and tear them back down again and it can’t be easy being buffeted by those forces at an age when a lot of people are still trying to figure out what they want to do with themselves.
